The 18650 Single Battery Cell Spacer/Holder is a high-quality modular spacer designed for building custom battery packs using 18650 lithium-ion cells. Constructed from flame-retardant ABS/PC material, it offers superior heat resistance, durability, and crack prevention, ensuring long-lasting performance. The holder’s interlocking side slots allow you to easily connect multiple spacers to form battery arrays of various shapes and sizes. Once assembled and spot-welded with nickel tabs, the structure remains stable, vibration-resistant, and suitable for high-performance applications like eBikes, power banks, robotics, and energy storage systems. Compact and easy to use, this spacer provides a secure and efficient solution for battery pack assembly. Featured By RoboticsBD.
